A team of planetary geologists who recovered a meteorite from a Western Australian farm believe there may be another significant piece to discover, potentially leading to further discoveries about Earth.

The 4.1-billion-year-old rock was taken to the university where it underwent CT scans and x-rays to determine its composition and makeup.

Dr Martin Towner from the university's Department of Applied Geology said early work had found the meteorite contained uncontaminated pockets of liquid water that could help researchers understand how water came to be on Earth.

"A lot of meteorites have got traces of water in them, as well as trace amounts of salt minerals," Dr Towner said.

"The problem is when a rock falls onto the Earth and spends months or years here, it gets rained on and gets weathered.

"But this one, because it was only on the ground for six and a half days, in a nice, dry place with no rain and no running water, well ... all those kinds of salt minerals and trace elements of water are preserved inside it.

"If we can compare that to the kind of water that's in the Earth's oceans, the various trace elements and the mix of those trace elements and isotopes, we can see if the two line up."

The meteorite is believed to have been 50 to 100 times bigger than its current size before falling through the atmosphere.

Dr Towner said due to the way the meteor dissolved and broke during its descent through the atmosphere, there may be further pieces to discover.

The team plans to return to the area in the new year.

"It's quite possible there's still another bit or two up there that we haven't found yet," he said.

"There are areas around that farm where they haven't cut their crops yet, so once the farmers have cut the wheat down, we will almost certainly go back and have a check out of the areas to make sure there isn't anything else out there."

The meteorite currently undergoing testing appeared to have had small pieces broken off as it came through the atmosphere, Dr Towner said.

"What we don't know of course is if there's another big piece or if you're just talking about a bunch of teeny bits.

"If it turns out to have a slightly different composition, then that gets really interesting in terms of trying to tie things all together."
